names that appear in the program that are defined in # define will be replaced with corresponding replacement text;2. The naming method is the same as the ordinary variable name, and it is a sequence of letters and numbers that begin with a letter;3. The replacement text can be any sequence of characters, not limited to numbers.So the above temperature conversion program can be rewritten as:#include /* Print Fahrenheit-Celsius temperature table */#de

\cdot k$, where $p _1$ is prime and $p 5. Find the $x $, $y $, $z $ for all primes that satisfy the equation $x ^y + 1 = z$.Answer:$x ^y$ differs from $z $ parity, so $x = 2$. $$\rightarrow 2^y + 1 = z$$ If $y $ is odd, then $z $ is composite, so $y = 2$, $z = 5$.6. Proof: $n > 2$, there must be a prime number between $n $ and $n!$.Answer:Easy to know $ (n!, n!-1) = 1$. The primes in $1\sim n$ can be evenly divisible $n!$ but not divisible $n! -1$, so $n! -1$ must contain a prime number that is

data.However, R also has shortcomings. Because it works in a programmatic way, it's not as easy as eviews and SPSS, and some simple work can be faster with those graphical tools. In addition, it is not as good as the interactivity of our frequently used Excel and OpenOffice documents, although this drawback can be overcome by exporting those documents to text documents, but it is a disadvantage.Here is the R code of a paper I've seen, which is a structural model that uses the two-phase least sq

shortcut to go. Only the daily repeated operation, often write code, we encountered problems in a certain way. Waste, learning programming language needs a relatively long period of time, can not skyrocketing rise, which requires a process, in the process of slowly accumulating experience, solid foundation. Do not think that you have written a simple small program, you think you have learned very well, this is just a little practice in your learning programming process. Do not be satisfied with
